I am having difficulties with SpywareBlaster on a new desktop with Windows 8 (64-bit) and IE 10. I am able to download the program and install it without any errors. It appears in my program list where I can successfully uninstall it (the modern version of Add/Remove programs). My first attempt: After SpywareBlaster finished installing, I left the "run now" tick box selected -- my hard drive began running (the amber light turned solid, not even a flicker) and never stopped. My system was unresponsive; I could not bring up the task manager to end task, log off, ctrl+alt+del or click on anything. After a few minutes, I was forced to shut down with the power button. My second attempt: I uninstalled the program, re-downloaded it and ran the setup again. This time, I unticked the box and restarted. When I tried to run SpywareBlaster, I had the same problem where the hard drive began running incessantly. Again, I was forced to shut down with the power button. I downloaded the program from FileHippo the first time and MajorGeeks the second to rule out a corrupted file. The only other security software on my system is Eset Smart Security 5. I used the combination on my XP machine with zero issues. I am almost afraid of trying again. Any suggestions on what is causing this? Thank you.
